# Unit 7 Exponential and Logarithmic Functions

## Understanding the Basics of Exponential and Logarithmic Functions

Exponential and logarithmic functions are mathematical concepts that are used to describe relationships between variables. Exponential functions involve the use of exponents and are used to describe exponential growth or decay. Logarithmic functions, on the other hand, involve the use of logarithms and are used to describe the relationship between two variables. In this unit, we will explore both types of functions in detail and learn how to solve problems that involve them.

## Exploring Exponential Functions

Exponential functions are equations that involve exponents and are used to model situations in which a quantity increases or decreases rapidly. Exponential functions can be written in the form y = b^x, where b is a positive number, and x is the independent variable. These functions can also be represented graphically, and the graph of an exponential function is always a curve that increases or decreases rapidly. In addition, exponential functions have the property that the rate of change of the function increases or decreases with the value of the independent variable.

## Exploring Logarithmic Functions

Logarithmic functions are equations that involve logarithms and are used to model situations in which two variables have a relationship. Logarithmic functions can be written in the form y = log_b(x), where b is a positive number and x is the independent variable. The graph of a logarithmic function is always a straight line, and the rate of change of the function increases or decreases with the value of the independent variable. Logarithmic functions also have the property that the rate of change of the function increases or decreases with the value of the logarithm.

## Solving Problems Involving Exponential and Logarithmic Functions

Solving problems involving exponential and logarithmic functions requires an understanding of the basic principles of each type of function. In this unit, we will learn how to use these principles to solve problems involving exponential and logarithmic functions. We will learn how to solve equations involving exponential and logarithmic functions, as well as how to use graphical methods to solve problems. We will also explore the properties of exponential and logarithmic functions and learn how to use them to solve problems.
